, STATE S." FATENTOEFICE;i I

In constructing a flushing device in accordance with the particular example illustrated as one einhodiment of my invention, a cas ng 15 provlded comprising the sepa rable members '10, 11, which are coupled together by any suitable means, as for-instance by a threaded connection as at 12.

tions 15ofthe service pipe, so that. the said casing is interposed at the proper point in the service pipe leading to the apparatus to be flushed, The casing has an enlargement as at 1 6, to accommodate and housecertain of. .the. operative elements of my device.

" Mounted 1n bearings -l7, 18 in the casing a valve 20 adapted to command the. outlet om the casing'by seating on a valve seat The members 10 and 11 termmate respectively in; tubular ends 13, 14, adapted to becoupled 1n any suitable manner withv secis a shaft 19 which constitutes the stem of 21. Adjacent to the inlet end of the casingthe valve 20 is provided with suitable means for rotating 1t by the pressure of the flowing water, and saidmeans is of a character to vary the amount of water passing. therethrough, and therefore to vary the extent ofturning movement that will be imparted to the shaft between the opening and closing 7 of the valve.

" In'the illustrated example, I haveshown illustration a water means, there being shown adjusting screws 24 for the purpose A compression spring 25 acting against a collar 26, or arranged m any other equivalent manner, normally tends to give the shaft a movement in the m 'the reverse direction against the action of the spring 25.

A starting device is prodirection of the outlet to seat the valve 20 Y ou its seat 21, and to move the shaft axially vided which, in the formillustrated in Figs. 1 and 2, consists of a starting lever 271011 the casing, said shaft carrying withinthe the end of the shaft 19; A movcmentof a shaft 28 that extends through suitable stuiiing boxes in the outlet terminal 13. of

' casing, and'preferably adjacent to said outlet end, amen-m 29"which lies adjacent to.

the lever 27 willQrock the shaft, 28 and its arm 29, and thereby move the"shaft.19

axially and open thevalve 20 to start the; flow of water through the casing on.

'nection with the shaft 19,1 provide a latch for holding the saidshaft inf-the position with the valve open,'"said latch being advantageously" in the form of a rockingcurved member 30, pivoted as at 32. De-

sirably the latch 30,- and a trip and other appurtenances co act ng therewit-h, are mounted in a housing-or removable inner casing 33 constituting aframe' for the m entioiied parts. The latch. and the parts immediately relating thereto may be assembled in.connection with the auxiliary housin'gand all placed in position, the said auxiliary housing beingin the form of a narrow domc open at the bottom side, the dome being adapted to rest at one end on a shoulder 34 and at the opposite end said housing mayrcst on the inwardly projecting end 35 of the member 11 of the casing, as clearly shown in Figs. 1 and '2. The latch 30 may be a gravity latch, or spring-actedfit is of a curved form and .its free end normally rests on a member 36'carried by the shaft 19, said member being desirably of a form to present acylindrical perimeter 37 and abevelcd face 38, the-arrangement being such thattlie flE-Qffilld of thelatch 30 normally 7 rests' on. the -perimeter-*37', j as in Fig. 1.

When, however, the-shaftl9zis moved axially .to move 'the valve' 20 away from the seat, the latch will drop'so' that its free end lics'adjacent to' the beveled face 38 of the desirably a \vorrnf-wheel 39 mounted to rotate v in the frame'ior ho1 1sing33, and carryinga' stud 40, or its equivalent,-'saidjworm wheel meshing. \vitha worm41 ontheshaft 19. The la tch,3 0 is "formed with a'projection 42f presenting a 'jcam surface 43 with which the stud.4 0 engages in the. rotation of the.

mm wheel 39. Any suitable spring may press on thelatch 30 as against a stud' 45, for instance, I I

With the described-construction it will be observed that upon throwing the starting lever 27, the valve stem will be moved axially, and with it the remainder of the shaft 19, the valve QOjIe'aVing its seat and moving to the position shown in Fig. 2,

,whereupomthe latch 30' will drop behind.

the shaft member 36 and hold the valve open; the waterv passing through the water wheel 22, or equivalent device, actuated by the pressure of the flowin water, will rotate the shaft 19 and with-it the worm 41, which in turn .will rotate theuworm. wheel 39 in the. direction of the arrow in Fig. 2, until finally the-trip stud 40 engages the-projec tion 42 to finally leave the surface 43, or

as it is termed in mechanics, to finally cam 01f from said surface. The contact of the trip'stud 40 will have raised the latch out of line with the member 36 and permitted the shaft and valve to move axially .under theaction of the spring 25, and thereby close the valve. i

In Fig. 5, a slightly different form of starting device is illustrated; in which the tripping lever 46 is in general of bell crank form,iand has an arm 47 on which rests the lower end of avertical pin 'or rod 48 hav-. ing a head 49, said pin 48. being surrounded by a-short standpipe 50 that rises from the outlet pipe 51, said standpipe beingjdesirably provided with a stufiing box 52. Obviously, downward pressure on the head. of

thepin 48 will rock the starting valve and position, and subsequentlythe shaft and its immediate appurtenances are placed in p'o sitipn, after which the member 11 of the caslng is coupled. '3. The construction also makes the operative parts readily accessible for repair.

Having thus described my invention, 1 3
